They make all their own drivers and assemble them in Canada. Cabinets are made in China, I believe though, as are those of many companies these days.
9 times out of 10 when I see a thread that says "XXXXX movie just blew up my sub!!" it wasn't the MOVIE or the SUB, it was the OWNER who caused the problem. This one doesn't sound like that was the case, but we don't know all the facts - was the sub calibrated? How big is the room? He says "0" adjustment on the receiver, but if the sub is at 100% gain in a large room, that doesn't mean much. It's also an older, used sub...though it is still under warranty, that doesn't mean you can damage something and expect it to be replaced. A warranty isn't a license to be an idiot (not calling anyone here an idiot either).
I'm sure GM didn't replace a perfectly working motor with a new one just because you said "I want a new one and it's under warranty." If they did, then I can see why they are a junk bond and nearing bankrupcy.
I've seen at least one other person say the same thing regarding this movie, and it was an SVS sub. I'm sure there are more out there, and it isn't limited to this movie. I DO have a limiter on my sub at 14Hz, and I've played this movie LOUD; scary loud.
*edit* I'm not intending to defend Paradigm specifically, but I don't disagree with their decision. So you don't buy from them anymore, I can respect that, but that doesn't mean you should trash the brand because you had a bad experience. Try out some of their higher end stuff; the quality is there, however I WILL say, I almost never recommend Paradigm's subs unless it is their higher ones - the PW2200 and Servo15. I've owned quite a few Paradigm products, from most of the lines, and I was never disappointed with their quality. The very few, minor problems I had were quickly repaired/replaced by my dealer. If you'll notice, I no longer own any Paradigm products, but manufacturing quality and warranty are not the reasons for that.
